Why is it that Newcastle cant even beat Derby?

It really make fans of Newcastle frustrated and sad. We cannot even beat a team like Derby which has not won a match away from home? It really makes me wonder what is happening to the players and manager Sam in Newcastle are really doing. For two games, they are doing wonders and when you expect them to win at home to a bottom team (Derby), they fumble again and again. Making me really sick and wonder why I am so stupit to support them in the begining? When I start to support them in 1995, with Alan Shearer and Les Ferdinand and Asprilla, they were really amazing and good. But look at them for the past five years are really disgusting. But a true fan will continue to support their team even when they are down. Lets hope they dont dissapoint again when playing against Wigan.
